This invention relates to the metal seals --that.; are used tor hermetically 'seallng bottles and has'partlcular reference toan "ii-volition described and illustrated in the" specification and drawings accompanying application No. 640,479, for

21st", 1923. I The-prior invention referred to was devised for the purpose oi providing a metal oi'the type rererredto above and for ensuring tl'iat a means for removing them would-always be ready at'hancl.

It consists of a metal cap-having a; shallow crimped side wall part'of which-'ls'extended to form a "specially shapedtag-in which is a slot adapted to receive the tail piece-of another cap which is used as a lever to force the cap off the bottle. If another cap is not available a plain thin strip of metal may be passed partly through the slot and used as a lever instead of the extended portion of another cap.

It has been found however, that in some cases the opening means are wrongly used in that after the tag upon one seal is passed through the slot in another tag the two bottles are simply pulled away from one another with the result that the tags pull apart without efiecting the purpose for which they were designed. V

The present invention has been designed to remove this disability and consists 1n providing a means whereby the extremity of one tag may be first inserted in the slot'ol another tag and having been turned so that the ends lie flat against each other any attempt to pull them apart will cause them to lock together. One methodof effecting this object is by providing each tag with a slot having downwardly and inwardly tapered sides the extremity of each tag being D- shaped the lowermost edge of the tag forming the curve of the, D. Therelative slzes of the' slot and the D-shaped end will in all cases be such that the latter maybe passed, through the slot in another'tag by fir-stentering one end of the D and then. giving 1t a circular movement in a. plane substantially at right angles to the other tag.

- In order that the invention will be properlv understood it will now be particularly described and reference will be made to the accompanying sheet of drawings. in which :-v

To remove the cap from a bottle either a o the -slot 1 in the tag spare cap or a cap securedupon another bottle and constructed according to thisin vention may be used. If the latter course is adopted each tag will be bent outwardly from their respective bottles sufficiently to enable the D-shaped end 11 of one cap to {be inserted in the slot 12 in'the other cap in a plane at substantially right angles thereto. In that position-the bottle upon which is the tag that is being inserted is then moved so as to bring the ends of the tags flat against each other as shown at Fig. 5 when it will be given'a further hinge-wise movement upon the tags until the caps themselves, abut against each other so that one of them may be levered off its bottle and as the resultant separating strain is brought to bear up'on the tags the extremities of the D-shaped end 11 will slide over the tapered edges 13 by which they will beenga ed on the opposite side to that from which they were entered.

1. A bottle cap comprising a body provided with a skirt portion adapted to embrace the mouth of a bottle, a tag carried by the body having a slot therein, means permitting the lateral introduction of the tag of a discarded cap into said'slot and also permitting the tag of said discarded cap to'bc subsequently moved in substantial alinement with the first mentioned tag whereby the tag of the discarded cap may beut-ilized as a lever for eifecting the removal of the first mentioned cap and a shoulder on the tag preventing the longitudinal withdrawal of the tag of the discarded cap through the slot of the first mentioned tag after the tags have been moved into alignment with one another.

2A bottle cap comprising a body provided with a skirt portion adapted to embrace the mouth of a bottle, and a tag carried by said body provided with a slot and a recess lyingoutwardly of said slot, said recess'defining a retaining shoulder facing said slot, said recess permitting the lateral seen-5e ing to prevent the longitudinal withdrawal of the tag through said slot.

3. A bottle cap v comprising'zg abody provided with a depending skirt portion adapted to embrace the mouth of a bottle, a tag carried by said body and provided with a slot adapted to receive'the end of the tag of a second cap, and shoulders carried by the tag adapted to coact with the walls of the slot to prevent the longitudinal withdrawalof the tag of one cap through the slot in another cap. o

i. A bottle cap as claimed in claim 3 characterized in that the tag is provided with'a recess lying contiguous to the shoulder permitting the lateral introduction of the tag of one cap into the slot of another cap and also permitting the tags to be subsequently moved into alinement with one another.

In testimony whereof I'have name to this specification.
